Is there a way to display the framerate in the BGE standalone runtime/EXE?
Have a look at the blenderplayer arguments

blenderplayer.exe

usage:   blenderplayer.exe [--options] filename.blend

Available options are: [-w [w h l t]] [-f [fw fh fb ff]] [-c] [-g gamengineoptions] [-s stereomode] [-m aasamples]
Optional parameters must be passed in order.
Default values are set in the blend file.
...
  -g: game engine options:

       Name                       Default      Description
       ------------------------------------------------------------------------
...
       show_framerate                 0         Show the frame rate
...
example: blenderplayer.exe -w 320 200 10 10 -g noaudio c:\filename.blend
example: blenderplayer.exe -g show_framerate = 0 c:\filename.blend
example: blenderplayer.exe -i 232421 -m 16 c:\filename.blend
